Making the AppController @interface

做App”界面

We’ll use the Interface Builder application to lay out the window’s contents and hook up variousconnections between AppController and the user interface controls. Interface Builderis also used to lay out iPhone applications, so time in Interface Builder is well spent no matterwhich platform you’ll end up programming for. We’ll add stuff to the AppControllerclass, and then Interface Builder will notice our additions and let us build the user interface.First, we’ll set up the header file for AppController:

我们将使用Interface Builder应用奠定了窗口的内容，把App和用户界面控件之间的variousconnections。接口builderis也用来奠定了iPhone的应用，所以在界面生成器的时间用得无论你最终会编程平台。我们要添加的东西的appcontrollerclass，然后界面生成器会注意到我们的补充，让我们构建用户界面。首先，我们将建立App的头文件：

There are two new quasi- keywords in there: IBOutlet and IBAction. These are actually just#defines provided by the AppKit. IBOutlet is defined to be nothing, so it disappears whenwe compile. IBAction is defined to be void, which means the return type of the methodsdeclared in AppController will be void (that is, returning nothing).If IBOutlet and IBAction don’t do anything, why are they even there? The answer is thatthey’re not there for the compiler: IBOutlet and IBAction are actually flags to InterfaceBuilder, as well as the humans who read the code. By looking for IBOutlet and IBAction,Interface Builder learns that AppController objects have two instance variables that canbe connected to stuff, and AppController provides two methods that can be the target ofbutton clicks (and other user interface actions). We’ll talk about how this works in a little bit.In Interface Builder, we’ll connect the textField instance variable to an NSTextFieldobject. This text field is where users will type strings to be converted, which is the typicalrole for an NSTextField.resultsField will be connected to a read- only NSTextField. When in read- only mode,an NSTextField acts like a text label. This text label is where the uppercase or lowercaseversion of the string will be displayed.

有两个新的准关键词有：IBOutlet和ibaction。这些实际上只是#定义由AppKit提供。IBOutlet定义是什么，所以它消失在编译。ibaction定义是无效的，这意味着在App的methodsdeclared返回类型将是无效的（即，返回任何值）。如果ibaction IBOutlet和什么都不做，他们为什么在那里？答案是他们没有编译器：IBOutlet和ibaction实际上标志interfacebuilder，以及人类阅读代码。通过寻找IBOutlet和ibaction，Interface Builder知道App对象有两个实例变量，可以连接到的东西，和App提供了两种方法，可以在目标ofbutton点击（和其他用户界面操作）。我们将谈论如何工作的一点。在Interface Builder中，我们连接的实例变量的nstextfieldobject。此文本字段是用户类型的字符串进行转换，这是一个nstextfield.resultsfield的typicalrole将会连接到一只nstextfield读。在读模式，一个nstextfield像文本标签。本文标签是字符串的大写或lowercaseversion将显示。

Because they play such an important role in your app, view controllers are at the center of almost everything you do. The UIViewController class defines the methods and properties for managing your views, handling events, transitioning from one view controller to another, and coordinating with other parts of your app. You subclass UIViewController (or one of its subclasses) and add the custom code you need to implement your app’s behavior.
因为他们在你的应用中扮演着如此重要的角色，视图控制器在中心几乎你所做的一切。UIViewController类的定义方法和属性来管理您的意见，处理事件，从一个视图控制器转换到另一个，并协调与您的应用程序的其他部分。你的子窗口（或它的一个子类）和添加自定义代码，你需要实现你的应用程序的行为。
There are two types of view controllers:
有两种类型的视图控制器：
Content view controllers manage a discrete piece of your app’s content and are the main type of view controller that you create.
内容视图控制器管理你的应用程序的内容离散块和视图控制器的主要类型，你创造。
Container view controllers collect information from other view controllers (known as child view controllers) and present it in a way that facilitates navigation or presents the content of those view controllers differently.
容器视图控制器从其他视图控制器收集信息（称为子视图控制器）和它的方式，促进了导航或内容不同的视图控制器。
